C-zoo li tus hlau yog ib hom hlau uas ua los ntawm txias dabtsi yog khoov los ntawm kub coil phaj. C- zoo li cov hlau muaj qhov zoo ntawm cov phab ntsa nyias, lub teeb yuag, zoo hla- ntu kev ua tau zoo, thiab lwm yam. Piv nrog cov tsoos channel steel, tib lub zog tuaj yeem txuag tau 30% ntawm cov khoom siv. Siv dav hauv steel qauv tsev purlins, phab ntsa kab teeb, kuj tuaj yeem ua ke rau hauv lub ru tsev truss, bracket thiab lwm yam khoom siv hauv tsev. Tsis tas li ntawd, nws tseem tuaj yeem siv rau txhua kab, kab teeb thiab caj npab hauv kev lag luam teeb pom kev lag luam.
Q hauv Q235 sawv cev rau qhov txwv tsis pub dhau ntawm cov khoom siv no, thiab 235 hauv qab yog hais txog cov txiaj ntsig ntawm cov khoom no, uas yog kwv yees li 235MPa. Thiab nrog qhov nce ntawm cov khoom tuab thiab nws cov txiaj ntsig tau txo qis, vim yog cov ntsiab lus ntawm cov pa roj carbon monoxide, kev ua haujlwm zoo dua, lub zog, plasticity thiab vuam cov khoom zoo sib xws, feem ntau siv dav. Feem ntau siv nyob rau hauv lub tsev thiab engineering qauv. Nws yog siv los ua steel tuav los yog tsim cov ntoo ncej, siab -voltage transmission towers, Choj, tsheb, boilers, ntim, nkoj, thiab lwm yam., thiab kuj yog dav siv los ua cov khoom siv nrog cov kev ua haujlwm tsawg.
Q235 siv
1. dav siv nyob rau hauv kev tsim kho thiab engineering lug. Nws yog siv los ua steel tuav los yog tsim cov ntoo ncej, siab -voltage transmission towers, Choj, tsheb, boilers, ntim, nkoj, thiab lwm yam., thiab kuj yog dav siv los ua cov khoom siv nrog kev ua haujlwm tsawg. C, D qib steel kuj tseem siv tau rau qee cov hlau ua haujlwm.
2. tuaj yeem siv rau ntau yam pwm tuav thiab lwm yam pwm tsis tseem ceeb.
3. kev siv Q235 steel punch cov khoom, tom qab quenching tsis tempering ncaj qha siv, hardness ntawm 36 ~ 40HRC, los daws cov punch hauv kev siv cov phenomenon ntawm cracking.
